Format Tab The Format Tab alllows you to select the format you would like to send your newsletter in. The ‘Text’ tab will send the newsletter in plain text format only, while ‘HTML’ format allows for additional formatting. ‘Text and HTML’ sends it as an HTML to customers whose email accept HTML formatting, and as in text format to customers whose email do not accept HTML formatting.dd
Transfer Protocol Transfer Protocol It is the way that the server sends the newsletter to your customers. The ‘Send Mail’ feature is the standard way to send the newsletter and no user name/password is required. Sending the newsletter using SMTP authentication is a better way of sending as it has a better delivery rate. This means that fewer recipients will see this message as spam, and will allow you to see any email bounces at the email you provide. To use the SMTP Authentication method you would need to have access to your website’s email account. Use an email account associated with your website, and enter the user name and password for that email in the boxes provided. This is the same information as using the Web Mail. You’ll also want to use this email under the "Contents" section.
The username would be your user name for the email account that you are sending the email from. This is the same information used to log into your webmail.
The password would be the password for the email account that you are sending the email from. This is the same information used to log into your webmail.
